Tenjo Kaito

Kaito Tenjo is a Numbers Hunter in Yu-Gi-Oh! ZEXAL. He is actually a nice person, but when his brother Haruto Tenjo fell sick, Dr. Faker told him that it was due to the "Number" holders and the Astral World. As a result Kaito became a Numbers Hunter. There is also a robot that accompanies Kaito which is known as Orbital 7.
